How to Determine if Your HVAC System is Compatible with a Nest Smart Thermostat

March 10, 2021

If you’re amid the average American households who spends more than $2,000 each year on utility bills, adding a smart thermostat is an excellent way to keep energy bills under control. Although most residences rely on programmable thermostats, yours likely isn’t being made the most of because it’s on “hold” every day.

When installing a new thermostat, the Nest smart thermostat is one of the most popular options. That’s since it learns your temperature preferences and routine, and then creates an energy-efficient schedule to match. You can also keep an eye on it and lower it from nearly anywhere with your smartphone.

For the typical home, Nest says its thermostat saves about 10-12% on heating expenses and about 15% on cooling costs. That’s about $131 to $145 saved each year, which helps the product pay for itself faster than two years. And the majority of utility companies offer rebate programs that help you purchase a smart thermostat for free or close to it.

When you’re upgrading to a smart home thermostat, you’ll want to make sure it’s compatible with your HVAC system. This is especially important if your equipment is getting old. If it’s not, you may experience issues, like weird furnace or air conditioner behavior. That’s why it’s important to have a specialist like LTS Plumbing & Heating Inc. help you choose a new thermostat and take care of your smart thermostat installation.

Here’s how to find out if the Nest will work with your HVAC system.

Nest Runs with Most Heating and Cooling Systems

The good news is that Nest made its thermostat to run with many different 24-volt systems, including older ones.

This involves heating and cooling systems that use:

  • Natural gas
  • Oil
  • Electricity

Before you buy a Nest, you can run the Compatibility Checker to provide a smooth transition. Once you’ve double-checked it’s a match, your Nest will work you through compatibility and wiring when you set it up.

The Nest Learning Thermostat can run with the widest number of home comfort systems, like heat pumps, furnaces and air conditioners. It also works with highly energy-efficient multistage systems, dual-fuel equipment, humidifiers and dehumidifiers, but you’ll typically need a professional like LTS Plumbing & Heating Inc. to handle the detailed wiring and setup procedures.

Does the Nest Require a C-Wire?

If you’ve read up on the Nest, you’ve probably run into info about the C-wire, or common wire. This wire runs your smart thermostat when it can’t draw enough power from the other wires.

If you don’t have a C-wire, it’s probably still okay to use a Nest. The company says its thermostats were made to consume little power. Most of the time, this means they can run properly without this wire.

Have a smart thermostat without a C-wire and noticing strange heating and cooling behavior? An HVAC professional like LTS Plumbing & Heating Inc. can install a C-wire for you.
